Materials Data on RbCrI3 by Materials Project
RbCrI3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Rb–I bond distances ranging from 3.73–4.18 Å. In the second Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine I1- atoms. There are a spread of Rb–I bond distances ranging from 3.74–4.15 Å. There are three inequivalent Cr2+ sites. In the first Cr2+ site, Cr2+ is bonded to six I1- atoms to form face-sharing CrI6 octahedra. There are a spread of Cr–I bond distances ranging from 2.77–3.20 Å. In the second Cr2+ site, Cr2+ is bonded to six I1- atoms to form face-sharing CrI6 octahedra. There are a spread of Cr–I bond distances ranging from 2.77–3.15 Å. In the third Cr2+ site, Cr2+ is bonded to six I1- atoms to form face-sharing CrI6 octahedra. There are a spread of Cr–I bond distances ranging from 2.77–3.15 Å. There are six inequivalent I1- sites. In the first I1- site, I1- is bonded in a 5-coordinate geometry to three Rb1+ and two Cr2+ atoms. In the second I1- site, I1- is bonded in a 5-coordinate geometry to three Rb1+ and two Cr2+ atoms. In the third I1- site, I1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two Cr2+ atoms. In the fourth I1- site, I1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two Cr2+ atoms. In the fifth I1- site, I1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two Cr2+ atoms. In the sixth I1- site, I1- is bonded in a 5-coordinate geometry to three equivalent Rb1+ and two Cr2+ atoms.
